adapted to cooperate with the springs which operate on the two ends or bearings of the
roll; to provide means whereby, in spite of this construction, the roll can, if desired, be
adjusted out of alignment to compensate for unevenness in the web coming from
the web roll; and to provide means whereby the two elements above mentioned can
cooperate with each other in one mechanism.
Wood teaches that all printing presses are equipped with rolls used for
tensioning the web and so are textile finishing and other machines. The tensioning rolls
are spring seated and are designed to keep the web, which runs at all times from a
more or less uneven paper roll, smooth and taut as it is fed into the press. When it is
desired to run only a half or quarter width web, it is usually run on one end of the web
roll, and therefore, tends to throw the roll out of alignment. This would be detrimental to
good printing and often causes wrinkles in the paper, due to the lack of uniformity of the
tension on the two ends of the roll. Wood's invention is designed to eliminate the
disalignment of a tension roll, especially when running a half or quarter width paper,
and also to provide for adjusting it out of alignment when found necessary due to
unevenness of the paper roll.
As shown in Figures 1-3, the web is shown as running from the paper roll 10 over
the tension roll 11 to the press. The roll 11 is long enough to accommodate a full width
